The Shear Strength Evaluation of the New Shear Connector by Push-out Test

Abstract

In a composite beam, a Shear connector is installed to resist the horizontal shear on the interface between steel beams and reinforced concrete slabs. The steel-wire-integrated deck plate slab is commonly used on the wide section beam. Then vertical bars are installed on the upper wire of the ends of the steel truss girder to ensure safety during construction. This paper develops a new shape shear connector which can replace the shear connector and vertical bar in a steel wire-integrated deck plate and evaluates shear strength by Push-out Test. 40 specimens were tested. Plate thickness and strength of concrete are parameters in Push-out Test. From the Pust-out Test, the new shear connector showed a higher shear capacity and ductility than a stud connector, and functioned as a vertical bar and shear connector.
